Chronic atrophic gastritis is categorized as “stomach pain” and “fullness” in Chinese medicine, and can be treated with moxibustion if it is caused by cold or deficiency cold. In Chinese medicine, stomach pain and fullness can be caused by cold, dietary injury to the stomach, deficiency of the spleen and stomach, and emotional and emotional disorders. Stomach pain is mainly characterized by pain in the stomach and epigastric region (the part of the stomach near the heart). Planktonicity is mainly a feeling of fullness and discomfort in the stomach and epigastric region. If it is caused by cold, it may be accompanied by fear of cold and love of warmth, aggravated by cold and alleviated by warmth, and light mouth without thirst. If it is caused by deficiency cold, it may be accompanied by vomiting of water (vomit is clear and thin liquid), fatigue (lack of spirit), poor eating, loose stools, tiredness of limbs, and lack of warmth of hands and feet. Moxibustion has the function of warming the meridians and dispersing cold (warming the meridians of the body to get rid of the cold in the body), eliminating blood stasis and dispersing knots, and elevating yang and lifting the sun (elevating and lifting the yang of the body to lift the sunken organs). It can be used clinically to treat various diseases caused by cold and blood stagnation and meridian paralysis. Therefore, moxibustion can be used to treat stomach pain or fullness that is caused by external cold or deficiency cold. However, moxibustion is contraindicated for pregnant women. It should be used under the guidance of a doctor, moxibustion is not a cure for chronic atrophic gastritis, and the disease should be treated in accordance with the doctor’s advice.
